Description

Technical Field

[0001] The utility model relates to the technical field of gasoline generators, in particular to a gasoline generator with a pull rod. Background Art

[0002] Gasoline generators are also called variable frequency drives or drive controllers. They use variable frequency drive technology to change the frequency and amplitude of the AC motor's working voltage to control the AC motor's speed and torque. They are common AC converters whose input and output are both AC. For ease of use, gasoline generators have been miniaturized to create pull-rod gasoline generators. Traditional pull-rod gasoline generators add a telescopic pull rod and a pair of rollers to the chassis. When they need to be moved, the rollers are used as fulcrums to lift the gasoline generator through the telescopic pull rod, making it easier to move the gasoline generator.

[0003] In the prior art, the pull rod structure of the gasoline generator is located at the top of the plastic shell and is often directly connected to the top surface. This structure causes the top plastic shell of the gasoline generator to be subjected to great stress. After the pull rod is used for a long time, the top of the gasoline generator is prone to deformation. Utility Model Content

[0004] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a gasoline generator with a pull rod which can increase the fuel tank capacity, enhance the structural strength of the pull rod installation part, and reduce the probability of deformation of the top plastic shell due to high force.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a gasoline generator with a pull rod, comprising a shell side panel, a shell back panel, a fuel tank, a pull rod and an operating panel, the shell back panel, the operating panel and the left and right shell side panels together form a plastic shell, the fuel tank is fixedly installed in the upper and middle part of the plastic shell, the pull rod is arranged between the plastic shell and the fuel tank, and a sinking platform is provided on the top surface of the fuel tank, and the pull rod just sinks into the sinking platform for limited fixing; the pull rod is provided with a tail mounting seat, and the tail mounting seat is fixedly connected to the plastic shell through a metal mounting plate; the two shell side panels are provided with mounting brackets, the shell back panel is provided with mounting holes, the metal mounting plate is clamped between the front and rear mounting brackets and the shell back panel and is fixed in the plastic shell through mounting bolts inserted into the mounting holes.

[0006] Preferably, the mounting bolts pass through the mounting holes, the metal mounting plate and the mounting bracket in sequence and are fixedly connected by clip nuts, so that the installation is convenient.

[0007] Preferably, the metal mounting plate is a rectangular long plate, with both ends fixed in the plastic housing, and a pair of screw holes in the middle for threaded connection with the tail mounting seat, so that the installation is firm and the overall force is balanced.

[0008] Preferably, the tail mounting seat is fixedly connected to the pull rod by a pair of screws arranged up and down.

[0009] Preferably, ribs for increasing structural strength are provided on the upper and lower sides of the mounting bracket.

[0010] The beneficial effects of the utility model are as follows: the pull rod is installed on the top of the oil tank and placed on the inner side of the plastic shell, and a sunken platform for placing the pull rod is provided on the top of the oil tank. On the one hand, the pull rod can be limited to the left and right, and on the other hand, the space can be made more compact, thereby increasing the capacity of the oil tank without changing the overall height dimension. By adding a metal mounting plate for indirect connection between the pull rod and the side panels and back panel of the shell, compared with directly installing the pull rod on the plastic shell, the structural strength of the pull rod installation portion can be enhanced, thereby reducing the probability of deformation of the top plastic shell due to large force.
